SILQ.

Specification of Letters Eatent. I Pamtignted Aug, 8 1922 Application filed September 2, 1920. Serial No. 407,821.

and figures of reference marked thereon,-

which form a part of this specification.

The object of this invention is to provide a novel construction of silo, provided with means for elevating the .ensilage and fordumping the same after elevation thereof.

With this object in view, the invention. resides, generally stated, in a silo having a vertically reciprocating carriage carrying a bucket, and means for-automatically tilting the bucket at a predetermined point in the elevation of the carriage, so as to dump the contents of the bucket. 1

The invention is clearly illustrated in the accompanying drawings which show a pre ferred form of embodiment of my inventive ideas. Briefly described:

Figure 1 is a view in elevation, largely in section, of a silo equipped with my im provements 8 Figure 2 is a horizontal sectional view on the line 2, 2 of Figure 1, looking in the direction of the arrows, and j c Figure 3 is a fragmentary view in elevation, partly in section, taken at right angles to Figure 1.

Referring now in detail to the drawings:

1 designates a silo which may be of any conventional construction and form, and preferably annular in horizontal section, and provided with a top 2, which may be conical, as shown.

Disposed in a vertical position inside the silo, and suitably spaced therefrom is a standard 3, preferably non-circular in cross section, and in this instance rectangular in cross section, and suitably secured against movement at the bottom thereof, as by a spike, or pointed pin, 4:, and suitablybraced at the top as by a rod 5, suitably secured to, and carried by, the vertical wall of the silo.

Carried at the top of the standard 3 is a yoke 6, secured, as by means of bolts 7 .17, a bucket 18.

to the standard, and forming a support for a pulleyti on a shaft 9,- projecting through the yoke 6. I

Passing over the pulleyS is a .cable 10, wound around a drum 11, carried by a bracket 12 toward the lower end of the standard 3, said drum being conveniently rotated in any suitableimanner, as by a crank 13. 1 i

.. The other end of the cable 10 is secured to a carriage movable on the standard 3. The carriage may be of any suitable .construction and in this instance comprises a sleeve let, encircling the standard ,3, and carrying anti-friction rollers 15, 15, movable on opposite faces of the standard 3. Secured to the sleeve 14: is a bracket 16 ,to

which is pivotally connected, as shown at Secured to the standard 3, toward the top thereof, is a wire 19, bent to provide two vparallelarms 20, 20, extending on a downward inclined and secured at their outer ends to the bottom wall of a discharge aperture 21 in the wall of the silo 1.

A slide, or chute 22, comprising a plate,

arms 20, 20, in this instance by having the sides of said plate bent aroundthe arms 20, 20, said slide 22 extending from the. aperture, or discharge opening, 21-toward the standard 3, as shown in Figure 1.

Preferably, the wire 19 passes,as shown in Figures 1 and 2,th rough a boss 23, carried by a sleeve 24:, secured to the standard 3, toward 'the'top' thereof, as by means of apin25. i

Suitable means are provided for automatically tilting the bucket 18 as the same approaches the slide 22, and in this instance such means comprise a rod 1 26, passing through the sleeve 24: and bent to provide arms 27, 27, which are curved longitudinally,

arms 27, 27 which constitute cams to tilt the bucket, as shown inFigure 1, toward the slide 22.

Continued upward movement of the caras shown, is carried and supported bythe afield having upstanding ed liege with the bucket WlllGtlllSE thebucketto be fully tilted so as to dump the contents 'thereof onto the slide 22. Asthe slide 22 is inclined, the ensilage dumped thereon'fi-om 5 the bucket 18 moves by gravity toward the,

aperture 21,:E1o1n which it escapes.
